When Tom is unable to stop Jerry from pestering a frightened Mammy Two Shoes, a new, faster, more efficient mouser is brought into the house: Lightning, a red-furred devil of a cat, so quick that he actually looks like a bolt of lightning!
Although, on the surface, Lightning appears to be the perfect cat, he is actually as untrustworthy and mischievous as Thomas, helping himself to the contents of the fridge as soon as Mammy's back is turned. However, being a rather smart cat, he frames poor old Tom, who is booted out of the house (closely followed by Jerry).
Miffed at being bested by the new arrival, Tom and Jerry team up to get revenge and earn their places back in the house.
A rather derivative adventure (and one that suffers from some awful re-dubbing by the PC police on my copy), Old Rockin' Chair Tom is full of the usual gratuitous violence one expects from the guys, but really doesn't offer anything particularly new to fans. There are a couple of reasonably funny gags involving the use of a magnet, but don't expect this one to stick in the memory for long.
